FCDMC Annual Precip. - Water Year 2006 - Maricopa...

ANNUAL HYDROLOGICDATA REPORT

VOLUME I: PRECIPITATIONWATER YEAR 2011

PREFACE

This publication presents precipitation data collected by the Flood Control District of Maricopa County's (FCDMC) automated ALERT system. This telemetered flood-detection network is located primarily throughout Maricopa County, Arizona with additional stations in Yavapai, Pinal, Gila, and La Paz Counties.

The data contained in this report were collected, compiled and edited by the Flood Warning Branch of the Engineering Division. Precipitation data include daily, monthly, and annual totals for 306 stations owned and maintained by FCDMC. The ALERT base station computers also collect data from various stations not owned by FCDMC - data from these stations are not included in this report.

Information contained herein is as accurate and complete as possible within the limitations of real-time ALERT data collection technology currently available. Wherever possible, footnotes have been included to identify questionable, estimated or missing data. Reliance upon the accuracy, reliability or authority of this information is solely the responsibility of the user.

This report is Volume 1 of a 3 volume suite entitled "Annual Hydrologic Data Report - Water Year 2011". Volumes 2 & 3 in order are [2] Surface Water Report; and [3] Weather Data Summary. Additional copies of this report, and copies of the companion volumes, may be purchased from:

INTRODUCTION

The following paragraphs describe the arrangement, collection, and compilation of data in this report:

1. Data is tabulated for each precipitation gage based on the "2011 Water Year" which began Oct. 1st, 2010 and ended Sep. 30th, 2011. Each data page represents one gage, and lists daily precipitation totals, monthly totals, cumulative rainfall by month, maximum daily values for each month, and the number of days with rain. The data pages are arranged in ascending order by gage ID number.

2. The unit of measurement for daily precipitation totals provided in this report is inches. Annual totals are also provided in millimeters.

3. An index of gage names, numbers, locations and other descriptors is included as Table I.

4. All of the data in this report have been reviewed and/or edited in an attempt to provide the most accurate data possible. Inaccurate data or recording time gaps are flagged with a footnote describing the time the gage was down, the cumulative rainfall count in millimeters at the beginning and end of the down period, whether or not rain fell during that time and whether or not monthly and annual totals were affected. For example, a footnote might read "Gage 5550 down from 2/12 03:40 (92) through 2/14 13:30 (94) due to a lightning strike; assigned 2 mm to 2/13", where the values in parentheses are the beginning and ending rainfall counts in millimeters.

5. Snow gages were in service during Water-Year 2011, consisting of a 4-foot tube mounted vertically above and attached to the tipping-bucket funnel. Consequently, gages above approximately 5,000 feet will show meltwater following the colder winter precipitation events.

6. Table II lists the sensors installed in the FCDMC ALERT System during Water Year 2011 and their installation dates. Table IV lists the annual rainfall total for each gage, sorted by ID number, along with Water-Year totals for 2010, 2009, and 2008. Table IV can also be used as a quick reference to determine which gages were installed during the Water Year, which had incomplete records and which had estimated totals. In the case of estimated totals, one or more daily totals were calculated using rainfall values from nearby gages and/or weather-radar estimates.

7. Additional and/or more detailed sensor data in hard copy or computer disk format is available for the gages listed in this report. Contact the Flood Control District, Engineering Division, Flood Warning Branch at (602) 506-1501. Data can also be downloaded from our web site at www.fcd.maricopa.gov/Rainfall/rainfall.aspx.

8. Note on data compilation: All the automatic rain gages in this network (except #6525) measure rainfall depth in 1mm increments. The base station computer that collects the data uses the relation 1mm = 1/25.4 or 0.03937 inches to convert millimeters to inches. As a result, daily totals may sum to a slightly different total than the reported monthly total in english units (which is more accurate than the sum of the daily totals) because of rounding errors. In the same way, the annual totals reported in Table IV may not match exactly the sum of the monthly totals, but can be considered more accurate.

9. Note on the accuracy of monthly and annual totals: Because automatic ALERT gages are designed for flood warning applications, there is some inherent error associated with their use in maintaining accurate long-term records. The majority of tipping buckets collect rainfall in 1mm increments before sending a signal and dumping the accumulated rainfall. Because evaporation often dries the bucket between storms, the measurement error averages out to be 0.05 mm (0.02 in) times the number of rainfall events during the period of interest (month or year). It is also probable that during times of low evaporation and/or short times between storms that the bucket could be partially or nearly full at the start of a rainstorm. Other errors can be introduced by the effects of gage height, calibration errors, and the physical environment (trees, buildings, wind patterns) near the gage - these are noted where known to cause inaccuracies.
